Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

NTSB Number
CEN21LA110
The pilot stated that he intended to depart from a soft, muddy runway and was having a difficult time becoming airborne. When the airplane reached a spot of the runway that was not as muddy, the airplane “popped out of the mud” and reached an altitude of about 30 ft above the ground. Before he could lower the nose to gain airspeed, the left wing stalled and the airplane impacted the surrounding terrain resulting in substantial damage to the fuselage, tail, and both wings. The pilot stated that there were no mechanical anomalies with the airplane that would have precluded normal operations.
NTSB Probable Cause
The pilot’s decision to takeoff from unsuitable terrain which resulted in an aerodynamic stall and subsequent impact with terrain.
